After 10 seconds the current is I o /2. After how many more seconds will the current be I /8 ? 2. When the current is I /2, what is the charge on the capacitor? 3. Draw a graph of the charge on the capacitor as a function of time. charge on capacitor: Q=CV energy in capacitor: U = CV 2 /2 Q(t) t (s)...
